Getting Started

1. Setup Environment Variables:

The server .env file --> server/.env:

• PUBLIC_URL should be a domain like https://mydomain.com for production, use http://localhost:3000 for dev, this points to the origin for requests, which is mostly the user's browser.

ETHERSCAN_API_KEY=
PUBLIC_URL=

The Next.JS app .env file --> .env

• PUBLIC_URL should be a domain like https://mydomain.com for production, use http://localhost:3001 for dev, this points to the backend for initiating the socket connection.

NEXT_PUBLIC_URL=""

2. Run Docker:

The frontend and backend are both containerized and meant to be run at the same time.

sudo docker-compose --build up

To deploy the app on a VM, I would start by making use of HAProxy to accept incoming https requests at port 443 and direct traffic to localhost:3000 & locahost:3001 accordingly. I would then use Certbot with a domain to obtain TLS certificates and have them automatically renew. HAProxy directing traffic to Docker containers & Certbot combined would be suitable for a lightweight production deployment.
